Assume body temperatures of adults are normally distributed. Based on this data, find the 95% confidence interval of the mean body temperature of adults in the town. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. Assume the data is from a normally distributed population. 95% C.I. =
A random sample of n1n1 = 228 people who live in a city were selected and 85 identified as a republican. A random sample of n2n2 = 101 people who live in a rural area were selected and 54 identified as a republican. Find the 95% confidence interval for the difference in the proportion of people that live in a city who identify as a republican and the proportion of people that live in a rural area who identify as a republican.

- [Econometrics] Assume that condition, or conditions, hold. Your task is to evaluate if, at the end of the day, the program had an effect on the household income per capita of the treated population with respect to those in the control group. Calculate the ATE of each program on the final level of household income per capita, assuming that all the individuals are compliers. • Evaluate if the effect is statistically different from zero at the usual confidence levels. For this case, the standard errors have to be calculated following the formula: o 07 SE пт + пс Page 2 where no corresponds to the sample size of the treated group, nato the sample size of the control group, or2, and očare the variances of the treatment and the control group. The values for them are given in table 2. Remember that the critical values in the t distribution are the following: For 90% of confidence the value is 1.646, for 95% of confidence the value is 1.960, for 99% of confidence the value is 2.576 and 99.9%…arrow_forward6.18 Is college worth it?
